Ok, it says pSeries 640 as a baseline of 1.0, which doesn't explain much.
I have 54.06 rPerf for 9119 and 123.97 rPerf for 9117 for these 2 servers.

I don't think 123.97 rPerf for 9117 is 2.3 ( = 123.97 / 54.06) times faster or more capable than 54.06 rPerf for 9119.

What will be the best to estimate 9117 is how many % faster or more capable
than 9119?

Please advise. Smilie
